1 Claim. (Cl. 38-59) This invention relates to ironing machines of thetype having a padded roller mounted on a stand and positioned to coactwith a heated shoe or buck, and in particular an ironing machine havingthree primary movements with the roller adapted to oscillate about itsaxis, rotate, and slide longitudinally whereby a plurality of ironingactions are obtained which make it possible to iron materials withsubstantially the same movements produced in hand ironmg. g

The purpose of this invention is to provide a universal ironing machinein which reciprocating movements are combined with rotary travel of aroll and in which substantially all types of materials and garments mayb ironed thereby.

Ironing elements of ironing machines have been provided of various typesand designs to compensate for dif-, ferent materials and articles to beironed thereon and to imitate ironing by hand, however, it has beenfound difficult to combine the rotary and sliding movements where thesliding movements are both transversely and longitudinally disposed.

With this thought in mind this invention contemplates an ironing machinehaving a roller mounted on an den-- gated spindle with the rollerpositioned to coact with a heated buck or shoe and in which operatingmeans are provided for elevating and lowering the buck, for oscillatingthe roller with transversely disposed movements,

for rotating the roller continuously, and also for sliding the rollerIOngitudinally on the spindle and in relation to the buck.

'The object of this invention is, therefore, to provide means forforming a combination or universal ironing machine in which a rollerjournalled on a spindle is rotated, and reciprocated transversely andlongitudinally and in which a buck, mounted to coact with the roller, isadapted to be raised and lowered to compensate for'dif-E ferentmaterialsor articles being ironed. I Another object of the invention is toprovide means in an ironing machine whereby an ironing roller is adaptedto be reciprocated transversely, reciprocated longitudinally or rotatedcontinuously in which the different move ments are controlled by camsand in which the cams are, selectively, actuated by clutches.

A further object of the invention is to provide'a univer-' sal ironingmachine in which the ironing roller is reciprocated transversely,rotated continuously, or reciprocated' longitudinally and in which theheated shoe or buck is.

one end thereof, a padded roller mounted to slide longi-.

tudinally and rotate on said spindle, a heated buck positioned above theroller, foot actuated means for elevating and lowering the buck, and aplurality of cam actuated.

clutches for engaging and disengaging operating devicesfor,selective1y,-actuating the different parts of the ironer.

The ironing machine has four cams, three of these cams being used toshift the position of the rotors. The cam at 38 is designated as thehorizontal oscillation rotor gc'am. The cam 38 is provided with a groove37 which is engaged by a projection 36,011 the arm 26 that is clampedtothe sleeve 12 that is slidably mounted on thespindle'. 11 for the roller10. The cam at 104 is designated as the vertical oscillation positioningcam. The cam 104 is provided with a groove 107 which is engaged by the:projection -108 of a slider 109. The cam at 96 is designated as thevertical clockwise positioning cam. The cam 96 .is provided with agroove 95 which is engaged by a projection 94 of a slider 93. The cam 71is designated as the horizontal oscillation positi'oning cam. The cam 71is providedwith a groove 70 that is engaged by a projection 69 on aplate 67 that is attached to the slider 65. The projections on thesliders engage their respective grooves in their respective cams as setforth to effect the operation of the various rollers,as will be laterdescribed.

I As illustrated in Figs. 8 and 9 an arm or lever 26 is clamped on thesleeve 12 between the collar 25 and a similar collar 27 with the portionof the sleeve positioned between the collars clamped in an arcuatesection 28 of the arm 26 with a complementary arcuate section 29 havinga base 30 and positioned in a recess 31 of the arm and having-a flange32 extended from the opposite end. The flange 32 is secured by bolts 33to a flange 34 on theupper endof the arrn 26 and the base 30 is securedto the arm 26 with bolts 35. The lower end of the arm 26 is provided aprojection 36 that extends into a groove 37 in a cam 38 on a shaft 39journaled in vertically disposed members 40 and 41 of an inner frame,with bearings '42 and 43. I

The supporting frame, of which the members 40 and 4 1 form parts isprovided with additional verticallydisposed members '44 and 45 which aremounted .on a base 46 and, as shown in .Fig. 4 the upper ends of themembers are connected with a horizontal member 47. Thefr-a-me is alsoprovided with an upper intermediate member 48, alower member 49 extendedbetween the members 41 and 44 and a connecting member 50 by which themember 40 is mounted on the member 41.

Upon rotation of "the cam 38 from the position shown in Fig. 4, theprojection36 on the lower end of the arm 26 follows the groove 37whereby the arm 26 moves'outwardly carrying the ironing roller 10 andsleeve 12 longitudinally of the spindle 11 whereby upon continuedrotation of the cam 38 the roll 10 reciprocates longitudinally.

The cam 38 is mounted on a sleeve -51, to which the sleeve is securedwith a set screw 52 and, as shown-in Fig. 4, the extended end of thesleeve 51 is provided with a jaw 53 of a clutch having a coacting jaw54. The jaw 54 is carried on one end of a sleeve 55 on the opposite endof which a clutch collar 56 is mounted, the clutch collar being heldagainst the flange 57 with a spring 58.

The arm 26 is also provided with a guide bar 59 that extends through aU-shaped bracket 60 that is secured to the frame member 40 with bolts61. The 'end wall 62 of 4 the housing is provided with an opening 63through which the.bar.59 may extend.

The clutch collar 56 is actuated by a yoke 64 extended upwardly from aslider 65 mounted on the member 49, as illustrated in Figs. 15 and 16,the slider 65 extending over the upper surface of the member 49 andhaving a flange 66 extended over the member; and the slider beingsecured on the member with a bottom plate 67 that is attached to theslider with screws 68. The plate 67 is provided with a projection 69"that extends into a cam groove 70 of a cam 71 and the cam 71 is mountedon a shaft 72 which is journaled in the frame members 41 and 44 withbearings 73 and 74, respectively.

The shaft 39 is rotated by a motor 75 through an endless belt 76 that istrained over a pulley 77 on the motor shaft and a pulley 78 on the shaft39, and the shaft 11 is rotated from the shaft 39 with a chain 79 thatis trained over a sprocket 80 on the shaft 39 and the sprocket 81 on theshaft 11. The sprocket 81 is secured to a sleeve 82 with a set screw 83and, as shown in Fig. 4, the sleeve 82 is-provided with a clutch jaw 84that coacts with a similarjaw 85 on a sleeve 86 on the opposite end ofwhich is afiange 88 against which a clutch collar 89 is held with aspring 90. The sleeve 86 is keyed to the shaft With'a key 91 and theclutch collar 89 is actuated by a yoke 92 extended from a slider 93slidably mounted on a member 48 and having a projection 94 extended fromthe lower side which extends into a groove 95 of a cam 96 on a shaft 97.

The shaft 97 is rotated from the shaft 72 with an endless chain 98 thatis trained over a sprocket 99 on the shaft 97 and over a sprocket 100 onthe shaft 72.

The extended end of the shaft 72 is provided with an index wheel orpointer 101 by which the shaft, with the cam 71 thereon, may be rotateduntil the projection 69 is in the high point 102 of the cam slot atwhich time the slider 65 is moved on the member 49 until the jaw 53 ofthe clutch is in engagement with the jaw 52 so that with the jaw 53secured to the shaft 39 with a key 103 the cam 38 will be rotated,moving the projection 36 longitudinally with a reciprocating actionwhereby the arm 26 longitudinally reciprocates the ironing roller 10.

At the same time the chain 98 rotates the shaft 97, turning the cam 96,and also turning a cam 104 positioned-on the opposite end of the shaft.

With the cams 71, 96, and 104 adapted to be rotated by the lever orindex wheel 101 these cams are adapted tobe set .so that the high pointof each cam groovemay be positioned to close its respective clutch,whereby the different movements of the machine are independentlycontrolled.

By this means a high point 105 of the cam groove 95 of the cam 96 isadapted to be set to close the clutch jaws 84 and 85 whereby the shaft11 will rotate .in a

clockwise direction continuously so that ironing may be continued in theconventional manner.

At the same time the movement of the member 101 may be continued to theposition illustrated in Fig. 4 in which position the high point 106 ofthe cam groove 107 of the cam 104 holds the projection 108 of a slider109 on the member 48 whereby a clutch jaw 110 is in engagement with aclutch jaw 111 on the inner end of a sleeve 112 on the end of the shaft11. With the jaws 110 and 111 'in engagement and with a sleeve 113 onwhich the jaw 110 is positioned keyed to the shaft '11 with a key 114the shaft 11 with the roller 10 will be reciprocated transversely.

The sleeve 113 is provided with a clutch collar 115 that 'is urgedawain'st a flange 116 by a spring117, and the collar 115 is actuated bya yoke 1'18 extended from the "slider ,109. 7

'As illustrated in Figs. 4a'nd '5 the sleeve 1'1'2 isprovide'd with alever 119 that is secured to the sleeve with aset screwv 120 in ahub'121 and the lower end of the lever is connected to a link 1% with ap'inf1'23. ,The

mam

opposite end of the link 122 is pivotally connected by a pin 124 to theend of an arm 125 that is secured to the shaft 39 with a set screw 126in a hub 127 of the arm. With the parts mounted as illustrated in Fig.rotation of the shaft 39 carries the arm 125 around a circle with thelink 122 moving the lower end of the lever 119 from the position shownin full lines to the position shown in dotted lines whereby the shaft 11is turned to an angle of substantially degrees. With the parts movingcontinuously from the position shown in full lines to the position shownin dotted lines and from the position shown in dotted lines back to theposition shownin full lines the shaft 11 oscillates or reciprocatestransversely. With the sprocket 81 mounted on the sleeve 82 the sprocketand sleeve are free to rotate with the shaft 39 as the motor is inoperation and a rotary motion is transmitted to the shaft 11 when thejaws 84 and 85 are in engagement. By the same means the shaft 11 isrecipro cated transversely or oscillated when the jaws and 111 of theclutch actuated by the cam 104 are in engagement, as shown in Fig. 4.

The inner frame in which the cam and clutch shafts are mounted ispositioned in an upper compartment or section of a housing forming thestand of the ironer with the base 46 of the frame positioned on a baseand with the upper portion of the frame supported laterally by threadedstuds 131 and 132, the upper ends of which are threaded into an upperplate 133 and the lower ends of which are threaded into the upper member47 of the frame. The end plate 62 is provided in one end of the uppersection of the housing and the plate 134 is provided at the oppositeend. The housing is also provided with a rear plate 135 and a frontplate 136 in which a door 137 is provided, as shown in Fig. 1. The door137 is secured to the plate 136 with hinges 138 and 139 and a latch 140.The plate 138 is secured to the side and end plates of the housing withscrews 141. The plate 62 is provided with an offset section having ahorizontally disposed portion 142 and a vertical section 143 and, asshown in Fig. 4, the portion 142 is provided with a slot 144 in whichthe arm 26 travels.

The plate 62 is also provided with a projection or indicator 145 that ispositioned to coact with the lever or index wheel 101 to show which camis in the operative position or in positions wherein the clutches areengaged or disengaged.

The ironer housing or stand is also provided with a lower back plate146, end webs 147 and 148 and an intermediate web 149. These parts aremounted on the base 20 and extend upwardly therefrom and, as shown inFigs. 1, 10, 11, and 12 the buck or shoe 13, which is carried by the arm18 extended from the post 17 is mounted on the rear plate 146. The post17 is slidably mounted or telescopes in a tubular section 150 and thepost is secured in adjusted positions with a set screw 151 in a collar152 on a mounting plate 153.

The lower end of the post 17 is provided with a foot plate 154 thatextends forwardly, as shown in Figs. 10 and 11, so that it is withinreach of a foot of the operator whereby the shoe may be held downwardlyupon the ironing roll 10 as the machine is in operation.

A foot crank 155 is provided for elevating the shoe and, as illustratedin Figs. 1 and 12 the crank 155 is pivotally mounted by a pin 156 inspaced vertically disposed bars 157 and 158 and, as illustrated in Fig.12, the post is elevated by placing a foot on a pedal 159 and pressingthe upper end of the lever downwardly, as shown in dotted lines wherebya roller 160 in the opposite end of the lever presses upwardly againstthe under surface of the foot plate 154. With the post and shoe in theelevated position a latch 161, pivotally mounted in supports 162 by apin 163 is urged inwardly by a spring 164 whereby one side of the plate154 snaps into a notch 165. By this means the post and shoe are retainedin an upwardly extended position and when it is desired to lower theshoe the latch 161 is actuated by placing a feet on a. projection 166extended from the outer edge thereof.

The post 17 is resiliently supported from the lower end of the tube 150with springs 167 and 168 on rods 169 and 170, respectively, the rodsextending through a bar 171 on the lower end of the tube 150 and alsothrough the ends of a bar 172 on the post 17. The upper ends of the rodsare provided with heads 173 and 174 and the lower ends with nuts 175 and176, respectively whereby tension on the springs may be adjusted. j

The front or cover plate 136 is provided with an ex tension 177 thatextends to the web 147 and the extension is provided with a knob 178 foradjusting the temperature of the shoe of the ironer and also a knob 179for actuating a switch to turn the circuit of the rotor on and off.

It will be understood that a conventional shoe or buck may be used incombination with the roll 10; however, as illustrated in Figs. 13 and14, the shoe 13 is provided with a cover plate 180 having an insulatingliner 181 and the cover is secured to the shoe with screws 182. The shoeis provided with end sections 183 and 184 in which the heating elementsare mounted with tubes 185 of insulating material. The heating elements,which in the. design shown, are in the form of coils are wrapped aroundtubular insulating ,rods 186 and 187 and the coils are connected to abrass rod 188 at the center. The rod 188 is also supported in the endmembers 183 and 184 with tubular insulating members 189. By this meansthe temperature of the shoe may be regulated as desired.

The shoe 13 is suspended from the arm 18 on the upper end of the post 17with studs 190, the lower ends of which are connected to a base plate191 that is connected to the cover plate 180 with screws 192 and, asshown in Fig. 13, the'studs extend through hubs 193 on the end of thearm 18 and the threaded upper ends of the studs are provided withadjusting nuts 194. Springs 195 are positioned between the lower surfaceof the arm 18 and shoe.

Figure 22 illustrates a typical connection of a wire of an electriccircuit to the electric heating element through the cover plate 180, thecover plate being provided with a threaded plug 196, of insulatingmaterial and the plug having a stud 197 secured therein. The lower endof the stud 197 provides a terminal 198 for a wire 199, and a connector200 on the wire by a screw secured against a nut 201 on the end of thestud. The stud is also provided with a projection 202 to prevent thestud rotating as connections are made thereto and the upper end of thestud is provided with a threaded section 203 on which a nut 204, ofinsulating material, is threaded. A wire 205 extends through an opening206 in the upper end of the nut and the end of the wire is secured tothe end of the stud 197 by soldering or other suitable means.

As shown in the wiring diagram shown in Fig. 2 the knob 179 actuates aswitch 207 one terminal of which is connected by a wire 208 to a sourceof current supply with the wire being connected to terminals of themotor 75 and the other terminal of the switch 207 being connected by awire 209 to the other side of the source of current supply. The wire 209is also connected by a wire 210 to one of the terminals, such as theterminal shown in Fig. 22, of the electric heating element and the otherterminal of the electric heating element is connected by a wire 211 to aresistance coil 212 of a rheostat or regulator 213. The oppositeterminal of the control device 213 is connected by a wire 214 to thewire 208. It will be understood, however, that current may be suppliedto the ironer by other suitable means.

As illustrated in Figs. 20 and 21 the shaft 72 may be rotated with awheel or lever, as indicated by the numeral 101, and the wheel may beprovided with points 215, 216, and 217 to correspond with high points ofthe area-37s cams,,.the high points being, indicated in the diagramshown in Fig. 20'.

With the machine designed and assembled in this manner three separateand distinct movements are accomplished such as an oscillating movementwith the roller rotating first in one direction and then in the otheracross or below theishoe or buck; a continuous rotary motion with thecylinder rotating continuously in the same direction; and third, alongitudinal reciprocating motion with the roller sliding longitudinallyon the shaft and under the shoe.

By this means substantially all types of garments and other articles maybe rapidly ironed on the machine, andin ironingd'ifiicult articles theoperator may readily shiftfrom one motion to another.

All bearings are provided with grease cups or fittings and 'as shown inFigure 2, threaded openings 3 are provided in .the frame for greasecups.
